Frequently Asked Questions

Everything you need to know about your Vortex water system

The Vitalize Cartridge restores four essential minerals stripped out during reverse osmosis filtration:

  • Calcium — supports strong bones and teeth
  • Magnesium — aids muscle function and energy production
  • Potassium — helps regulate hydration and heart health
  • Sodium — maintains fluid balance and nerve function

Together, these minerals restore your water to its natural mineralised state, making it better for you and noticeably better tasting.

This cartridge is specifically designed for the Vortex Air H2 Oasis Reverse Osmosis system.

It’s not a universal filter, so it should only be used with compatible H2 Oasis units to ensure proper fit and performance.

Not at all. You simply just push it in and you're ready to go.

For optimal performance, we recommend replacing the Vitalize cartridge every 3 months.

This helps maintain consistent mineral balance, water quality, and taste over time.

No complicated setup is required.

Once you have replaced the Vitalize cartridge you simply press and hold the reset button.

Yes. The Vitalize Cartridge restores essential minerals and turns the water alkaline, giving it a softer, smoother, cleaner taste. Without it, reverse osmosis water can taste flat and empty, with it, your water tastes the way water should.
